Original Tetris

Tetris is a computer game invented by Alexey Pajitnov in 1985 at the Academy of Sciences in Moscow, Russia. Tetris was part of the classic handheld Game Boy console.

The objective of Tetris is to complete full solid lines (no gaps). When you make a line it disappears and all the blocks shift accordingly. If you let the blocks reach the top of the Tetris board, you lose. You cannot win a Tetris game, though you can attempt to get the high score.
